Abstract

PCT No. PCT/SE86/00252 Sec. 371 Date Feb. 5, 1987 Sec. 102(e) Date Feb. 5, 1987 PCT Filed May 30, 1986 PCT Pub. No. WO86/07582 PCT Pub. Date Dec. 31, 1986.The invention relates to a hook assembly of the type comprising a lifting eye bolt (2) and a hook (4) mounted in either end of a body (3), and a combined latch-ejector unit (31) rotatable between a first position for locking the opening of the hook (4) and a second position for uncovering the opening of the hook and releasing a load suspended therein, and with operating means (24) for adjustment of the latch-ejector unit between the said positions. According to the invention the hook (4) is firmly mounted in the lower end of the body, the lifting eye bolt (2) is mounted with limited mobility in the upper end of the body (3) and at least one energy-accumulating member (15) is operatively inserted between the body (3) and the lifting eye bolt (2) for storing energy therein upon relative movement between the lifting eye bolt and the body due to the application of load to the hook assembly (1), the energy accumulated in the energy-accumulating member (15) upon subsequent relief of the load from the hook assembly being transferred via a locking and transmission link system (12, 18, 21) to the latch-ejector unit (31) for adjustment thereof between the first and second positions.
